Hey guys!
So.... I figured second laser, very much like my first one, so set up should be a piece of cake... yeah... that's not happening.
#1: For the life of me I can't get the mirror that the laser hits first (ie next to the tube) to align with the next mirror (ie, the Y-axis / up - down). I spent all day on this (literally) and couldn't get it done, and I do know how to align a laser. When the Y-axis mirror was close to the 1st mirror, any small movements on the adjustment screws wouldn't move the dot. So to move the dot I have to make large movements on the screws. But when I moved the mirror away from the first mirror (towards the operator) the large movements push the dot way of center. When I adjusted the mirror to compensate it messed up the close alignment too much. In short I could get the dots close (when the second mirror was close t the first mirror, it needed to go up and to the right, and when it was far away it needed to come down and to left) but never overlapping.
Based on my experience and how long it takes to align my shenhui I'm pretty convinced that something else is going on, but I don't know what. I'm thinking something some where isn't square or possible level? I don't know. Thoughts?
#2 The bottom of the nozzle on my shenhui unscrews and holds the lens. On the new machine, when I unscrew the nozzle the lens is still in the tube, so I have to remove the tube from the assemble to get at the lens. Does the amount of the tube that is in the assembly matter?
Meaning, if the distance from the bottom of the assembly to the end was 3 inches, and then when I put it back in I push it up so now it's only 2 inches does it matter? I can't think that it would since when the light hits the top of the lens and and exits out the bottom, it's that distance (from the bottom of the lens to the material) that makes up the focal distance.
Thanks!
Walt
